PerMix ATMO

Portable Calibration Gas Generator
PerMix

Based on permeation tube technology combined with precise mass flow controllers, and built-in purified air generator, PerMix ATMO is unique all-in-one calibration solution for laboratory, mobile labs or remote locations use.
This portable device contains all components to assure the autonomy of operation including built-in computer, air pumps, mass flow controllers, and rechargeable battery power supply. Large touch screen enables easy operation. Ethernet connectivity provides remote control.
PerMix ATMO produces a very pure, accurate and repeatable calibration gas with programmed concentrations down to trace levels.

BENEFITS of PerMix ATMO :

  • Transportable and battery supplied
  • Complies to ISO 6145-10
  • Automated calibration sequences for linearity and repeatability checks
  • Ready to use : temperature and flow are maintained during transportation
  • Wide range of concentrations generated on-site
  • Robust design
  • Ease of operation enables use by nontechnical personnel

Self-contained
With two built-in pumps no cylinder supply is required: a low flow pump permanently sweeps permeation tubes to keep the concentration, one high flow pump (5L/min) provides zero air for dilution. Flow rates are adjustable by the software and regulated by precise mass flow controllers (MFC).
Time saving
Even during transportation the PerMix ATMO maintains operation conditions using its own power source: ovens are maintained at the temperature and purified air flow constantly sweeps the permeation tubes. When arriving on site just 2 to 3 minutes are necessary to switch the pump, stabilize the setpoint and calibration can be fulfilled without delay significantly saving the operator time compare to the traditional method.
Automated
Equipped with a touch screen and user friendly software the instrument operation is simple. The operator sets up a sequence with desired concentrations and the software determines dilution rates. When connected to the analyzer, the unit generates complete calibration program without operator intervention.
Versatile
With dual ovens with adjustable temperature setpoint and regulated flow, the system can accommodate most of the permeation tubes available on the market. With the capability to regulate individually the air flow in each oven, it is possible to use of different permeation tubes to create multicomponent mixtures. In addition, the PerMix ATMO has built-in diluter that can provide a dilution factor up to 1:100 with output flow up to 3000NmL/min allowing wide range of concentrations.

The PerMix ATMO provides an automated, cost effective way for on-site calibration and linearity checks of toxic gas detectors, automated measuring systems (AMS) to monitor emissions of greenhouse gases and air pollutants such as NO2, SO2, COS, BTEX, H2S, NH3 , other gas analyzers and chromatographs.
Self-contained for remote or field use it eliminates a need of multiple cylinders saving space, cost and removing safety hazard.
The PerMix ATMO is an ideal solution to generate calibration gas or mixtures of unstable or reactive compounds that are typically not available in cylinders.
